August 18, 1886, No. 74,262; in Germany August 21, 1886 No. 38,799, and in Bnglancl'Augnat 23, 1886,.110. 10,7618.

Be it known thatI, EUGENE ALFRED DU: RAND, a citizen of the French Republic-,and a resident of Paris, France, .have invented certain Improvements in Cigarette-Machines,

(for which a patent has been grantedin France, No. 171,805, datedOctober 22, 1885; in GreatBritain, No. 10,763, datedAugust 23, 1886; in Belgium, No. 74,262, datedAugust 18, 1886, and in Germany,"No. 38,799, dated August 21, 1886,) of which the following is-a specification.

My invention relates to that class of cigar ette-machines wherein the roll of tobacco or other material to form the cigarette is formed by lateral pressure between two semi-cylindrical fluted faces, and is then driven out longitudinally into a'previous'ly-formed tube of-paper or the.like; and the object of the invention is. to produce a durable and compact machine,'easily-operated and adapted to be'lubricated without danger of contaminating' the material of which the roll is formed; 1"

My invention will be fully described hereinafter, and its novel features carefully defined inthe claims.

:In. the accompanying drawings, illustrative of any-invention, Figure 1 is an elevation of the front ofia machine embodying my im' provements. Fig. 2 1s a verticaltransversesection of the machine seenin Fig. 1-, taken in the planeindicated by the dotted line 22 in Fig; 1. Fig. 3 is an end ele'vationjof the machine, showing the end'at the right in Fig. 1. Fig. 4 is a transverse section of the body or'operative portion of the machine, taken in the same plane as Fig. 2, but on a scale double that of the principal figures. I This viewshows the operative parts of the machine in. a position different. from that. seen in Fig. 2. Figs. 5, 6, 6 and 7 are detail views on the same scale as Fig. 4.

These views will be hereinafter described. X is a stout bed-plate of any kind, in which is formed a parti-cylindrical or trough-like seat. This bed plate or piece has heads or ends a; w, and between these is 'fixeda cylindrical core X, which is concentric-with the 'parti-oylindrical seat in the bed-piece-X. Be-

tween the core and seat is an annular space. E is a parti-cylinderor envelope, which rests Q and fits exterior-1y the seat-in .thebed piece and is provided with an operating-handle L, whereby this parti-cylinder or envelope may be turned about its axisin its seat.

VVith in the part -E andoccupying the resi due of-the annular space between the concave bed-piece and the core X are the two parti-cylindrical demi-molds or mold-sections T'and T.

Thesection T is fixed in position by attachment to the core; butthe section T is free to, move about the core to a iimited.

-or other substance from which the cigarette.

isto be made, andthese opposed faces or.

edges of the sectionsT and T, which efiect the compression and molding, have each a semi-cylindrical concave matrlx, whereby,

when they are broughttogether. on thematerial, they niold'itinto the form of a cylinder or roll.

Movement isimparted to the mold-section T through the mediunrof the part E in the mannerfollowing: In the envelope is formed a slot a, and in the section .1 is fixed a projecting stud or screw t,whi ch projects outwardly intoand engages the slot a.v This en- 'gagement'of the screw t with the slot in the envelope causes the section T topartake of a part of the movement of the envelope E, but not of the whole movement.

, Fig. 2 shows the mold open. The tobacco or other material is placedin the spacey and thehandle L is pushed over. toward the right inFigs. 2 and 4.. The first-effect is to move the envelope E about and independently of the section T by reason of the slot a; but when the end of this slot engages the stud t the mold-section T moves with the envelope, and this movement is continued until the matrices of the mold-sections are together, as seen in Fig. 4, and the tobacco between them is formed into a roll Z, ,as-seen in the figure. Before the mold-section T has completed its movement, however, the advancingv lip or margin 6 of the envelope E will have'passed over the ing compressed, so that it cannot protrude.-

and be nipped between the faces of the moldsections, and' at the same time to enable the lip or margin 6 of the envelope E to drawback and leave a clear space for the insertion of the material into the mold. When the compression of the roll is being effected, a projecting lug e on the envelope E strikes on the crown, of a spring-butferDe (Seen detached in Fig. 7.) This buffer is adjustable, so as to regulate the pressurev to be put on the material, and it comprises as its elements an upright cylinder fixed to the base and containing a coil-spring, a follower :restingon said spring and provided with a slot/which is engaged by a pin in the cylinder, which thus-forms alimiting-stop, anda steel screw in the topof the follower for the lever L to impinge upon. This screw permits of regulating the extent of movement of the lever L under a given force applied thereto.

'. To hold the mold closed on the roll of material a spring-latch is provided, as best seen in Figs. 2 and 4. A latch-lever A is pivoted to the base of the machineand provided with a holdin g-spring B. This latch bears elastically on the envelope E, and atooth cthereon wipes over and engages the projecting end of the stud t or some suitable projecting part. I have described above the roll-forming mechanism, and will now describe the mechanism employed for discharging or ejecting the roll from th'e'matrix of the mold and fore;

ing. it into a previously-formed tube of paper or the like.

N is a rod or plunger axially aligned with the roll Z in the moldand of the same size asthe roll. This plunger is adapted to be pushed longitudinally through the mold by inside the ,casingMbears on the head of the a spring. 7

On the end frame of the machine is secured a tubular spring-casing M, over which plays orslides' a sleeve 0, which is'connected with the plunger N inside of the casingM by means of a screw or stud g through-along? tudinal slot h in the casing. The spring .11

plunger N. The plunger is retracted and the spring compressed through the medium of the sliding sleeve 0, and said plunger is held in position drawn back'by a lock formed by a'lateral branch h of the slot h, with which the stud g is made to engage by a partial rotation of the sleeve 0 and of theplunger secured thereto.

While the roll Z is being compressed and formed the plunger N stands drawn back or retracted; but after the molding is effected a previously-formed tube 2, of paper or the like, is placed in position to receive the ejected roll and the plunger then released, when the latter will drive out the roll and form a cigar ette. The plunger may then be retracted, another roll formed, and the operation repeated. v

The supporting devices for the tube z are illustrated in Figs. 3, 5, 6, and 6. In Fig. 5, which is a sectional view of one end as of the the roll is ejected, and the tubular nipple m" on the end of the base w, on which the tube hold this ,end of the tube firmly in place while the roll is entering it a spring P (seen best in Fig. 3) is secured to the envelopeE in sucha position that when theroll is under pressure, as in Fig. 4, this spring will bear onthe tube at the point where the latter embraces the nipple w' and the nipple. i

,To support the outer. end of the'tube 2 an arm P (seen detached in Figs. 6 and is mounted to slide on a fixed rod P on the machine-frame. This arm P may be set at any point on the rod which will best adapt it thus hold said tubefirmlyon- 2' is slipped to receive the ejected roll.; To

parti-cylindrical mold-section, and themovable parti-cylindrical envelope embracing the said mold-sections and connected with the movable mold-section, substantially as set forth. 2. In a cigarette-machine, the combination, with the. mold, of the slotted "tube M, the

arranged therein and aligned with the mold, the sleeve 0 on said slotted tube and connected with the plunger, and the locking device for holding the plunger retracted, all arranged substantially as set forth.

3. In a cigarette-machine, the combination, with the fixed core, the stationaryand-mova- 4:. Inia cigarette-machine, the combination, with the core, the fixed and 'movable mold sections, and the oscillating envelope E, the latter provided with an operating-handle and a projection e, ofthe spring-butter D, set in the path of the projection e, as and for the purposes set-forth.

5. In a cigarette-machine, the combination, with the molds,the oscillating envelope E, and

the fixed end frame provided with a-tubular' nipple an", arranged opposite to the matrix of the mold to receive the cigarette-tube, of the spring F on the envelope E, arranged in position to bear on the said nipple-when the mold is closed, substantially as and for the pur-' poses setforth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
